These two views have always existed in numerology and nomenclature, and it is reasonable to supplement the missing five elements or the use of gods. At the beginning, my point of view was to supplement the use of God. Later, it was found that people's use of God sometimes changed with the Universiade, that is, the use of God changed with the Universiade. Does it mean that every step of the Universiade has to be renamed? So I later added the missing five elements.
When God is weak, it is useless. When there is nothing, only obey the most prosperous five elements. This is the way of numerology and survival.
